3rd Gen Hood Louvers

I am now officially intrigued.

 

Wooo so in this could help keep a induction device Cool

 

Props to you for being original, but damn that looks like a house floor vent.

 

That took balls. I'm impressed.

 

Love it

 

Still need to paint the edges and secure, but you get the idea. I love it!

 

Have you thought about color matching them?

 

They came bare metal, I painted them black.

 

Lookin' good!

 

My wife calls it stupidity

 

Major props to you for cutting open your hood, doesn't look as bad as I thought it would Can they be closed or are they fixed?

 

Did we cover the "what about water pouring in when it rains" thing yet?

 

Mine too. Btw...nice look. Screw the science.

 

Not yet, curious as well. Don't want water soaking the electronics or dumping around the spark plug coils while driving (it can seep right on in)

 

I think color matching it blue would look awesome

 

You've had the balls to go this far.......now is the time to take it all the way brother!

 

Bought these aluminum louvers for a previous tundra but never had the balls to cut holes in the hood

 

Always kinda liked this rubicon hood and toyed with the idea of buying one, cutting it out and adding to the stock hood.

 

Looking good! It's about what I'd imagine a CFD sim would have come up with anyways. (or at least in the ballpark!)

So interestingly enough, those louver fins sit proud of the hood surface so I think they are basically acting as their own gurney flaps:


The idea behind such protrusions is they create a low pressure zone on the outside of the louvers which causes air to evacuate from under the hood much faster when you are at speed. Without these, the attached flow over the hood is going to act as a "barrier" almost, keeping outgoing air to a minimum.
